Hand of the Cause of God Dr. Rahmatullah Muhajir’s greatest desire was to serve his beloved Guardian, Shoghi Effendi. He understood the urgency of the times, the hunger of the millions of waiting souls who long for God’s healing message of hope and unity. He, perhaps, was the greatest mass teacher of the Bahá’í Faith in the twentieth century, bringing thousands into the fold of Bahá’u’lláh. For those who want to be inspired and encouraged – this book is a must.
